Sequential Hill's diversity index

Hill's diversity index.

HillS(rasterm, w, alpha, na.tolerance, debugging)

`rasterm`	input data.
`w`	half of the side of the square moving window.
`alpha`	alpha value for order of diversity in Hill's Index.
`na.tolerance`	a numeric value (0.0-1.0) which indicates the proportion of NA values that will be tolerated to calculate Hill's index in each moving window over x. If the relative proportion of NA's in a moving window is bigger than na.tolerance, then the value of the window will be set as NA, otherwise Rao's index will be calculated considering the non-NA values. Default values is 1.0 (i.e., no tolerance for NA's).
`debugging`	a boolean variable set to FALSE by default. If TRUE, additional messages will be printed. For de-bugging only.

Matrix or a list of matrixes with the Hill index computed through moving window of the given size.
